Attraction
Hagia Sophia
Justinian's sixth-century domed basilica, now the Hagia Sophia Grand Mosque, with a separate visitor route through its upper galleries above the prayer hall.
The 14th-century Genoese stone tower above Karaköy, now a museum with a 360-degree observation deck over the Golden Horn, Bosphorus and old city.
Good to know
The Galata Tower was built by the Genoese colony of Galata in 1348, as the high point of the walls around their trading settlement across the Golden Horn from Constantinople. Under the Ottomans it served variously as a prison, an observatory and a fire lookout, and its stone cylinder and conical cap are now one of the defining shapes of the Beyoğlu skyline.
The tower operates as a museum, with exhibition spaces inside telling the story of the building and the district. One well-known episode is the legend of Hezarfen Ahmed Çelebi, said to have flown with artificial wings from the tower across the Bosphorus in the 17th century. The real draw, though, is the narrow balcony that runs right round the top, giving a full circle of views across the Golden Horn to the mosques of the historic peninsula, along the Bosphorus and over the rooftops of Galata and Karaköy.
The tower is open every day from 08:30 to 18:15, with the box office closing at 17:45. There is also an evening session, the Night Museology Experience, from 19:00 to 23:00, with the box office closing at 22:00. Tickets are priced in euros, and visitors under 18 must be accompanied by a parent or guardian. Numbers on the balcony are limited, so queues can be long, especially around sunset.
Allow 45 minutes to an hour including any wait. Arrive at opening time for the shortest queue, or come for the evening session to see the city lit up. The balcony is narrow and busy, so keep a firm hold of phones and cameras and be patient for a spot at the rail. An audio guide is available through the museum's app.
It suits first-time visitors, photographers and anyone wanting to get their bearings. The tower stands in a small square at the top of Galata, a steep walk up from Karaköy tram stop or down from the Tünel funicular and Şişhane metro station. The surrounding lanes are full of cafés and small shops, Nardis Jazz Club is just downhill on Galata Kulesi Sokak, and the Kamondo Steps and Istanbul Modern are within a short walk towards the water.
Daily from 08:30 to 18:15, with the box office closing at 17:45.
